I once bought a cup of coffee for a homeless man, and he gifted me a USB Pendrive, after asking if I have a computer. I had a computer at that time, and I could use it. I do not remember the capacity of the USB pendrive. Maybe it was 1 GB, but it does not really matter. I saw that the person was grateful and happy. Not every homeless man is like this. Many homeless people do not accept foods and drinks. They just look for money. Mostly to buy alcohol.
